Atoy car moves around a circular track at constant speed. it suddenly doubles its speed — a change of a factor of 2. as a result, the centripetal acceleration changes by a factor of (a) 1/2.(b) 4.(c) no change since the radius doesn't change.(d) 2.(e) 1/4.

option B

Explanation:

given,

toy car is moving in circular track

speed is doubled— a change of a factor of 2

to find change in factor of acceleration

radius doesn't change

centripetal acceleration formula

           =

velocity is change in factor of 2

so acceleration will be change at the factor of

           =

           = 2² = 4

so the correct answer is option B

can u provide the graph and if its not possible

then i can tell u the segment where the

average time interval starts degrading is the segment where the car is slowing down
